Answer:
the goal is to try and get x alone. For the 1st problem, x=3.
Step-by-step explanation:
3x + 1 = 10 Subtract 1 both sides to cancel out the 1 on the left side. 10-1 = 9
3x = 9 To get x alone here, Divide 3 on both sides. 9/3 = 3
x = 3 Now x is alone, which means x = 3.
This is right because if you plug x with 3, the sum = 10.
(3*3) + 1 =10
9 + 1 = 10
So, that's how you know 3 is the right answer.

1. The formula for calculation of the volume of the cylinder is V=π*r²*h, where r - the radius of the base, h - the height of the cylinder.
2. According the formula above:
V=π*64*8=512π (cm³).
Answer: 512π
